とあるDebianのサーバーで，mysqldというか実態はMariaDBのデーモンですが，それがなかなか動いてくれなかったのを動くようにしました．<\/p>\n\n\n\n
問題は，\/runからもはや\/var\/runへsymlinkが張られていなくて，それぞれ実体のあるディレクトリーとなっているのに，mariadb.service内では，\/var\/run\/mysqldを使い，\/etc\/mysql\/mariadb.cnfでは\/run\/mysqldを参照しているためのようです．<\/p>\n\n\n\n
他のDebianのマシンでは，\/var\/runは\/runからのsymlinkなので，何かの手違いで，\/var\/runと\/runを独立させてしまったようです．<\/p>\n\n\n\n
システムが活きたまま，\/var\/runを\/runからのsymlinkに修正するのはちょっと危険ですね😓 <\/p>\n\n\n\n
と，いいつつ，やってしまいました．<\/p>\n\n\n\n
cd \/var\/run\ncp -Rdvp * \/run\ncd ..\nmv run run-save\nln -s \/run<\/pre>\n\n\n\n今のところ問題ないみたいです．<\/p>\n","protected":false},"excerpt":{"rendered":"
